PARLOR HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 311,140, dated January 20, 1885. Application filed November 7, model.)

To aZZ whom it may concern.-

Be it known that we, J. ALLISON ORR and HENRY SEIVARD, citizens of the United States, and residents of the city of Reading, county of Berks, State of Pennsylvania, have invented a new and useful Improvement in Parlor Heating-Stoves, of which the following is a specification.

This improvement relates more particularly to double fire'pot rectangular stoves, adapted to heat a room above the one in which it is placed, a pipe and register being provided for that purpose, or the pipe-hole may be closed directly by a register and the heat distributed in the same room; and its distinguishing feature is the hot-base arrangement, as the opposite of the cold-base heater of the same form of stove, shown in a prior application, known as Serial No. 91,618, of 1883.

The object of the invention is to secure all the heating effect of the fuel, and to increase the radiating effect of the shell of the stove by utilizing all parts thereof.

The general outline of the stove is as shown in Figure. 1, Sheet 1, and a cross horizontal section would be square or rectangular.

In the accompanying drawings, forming a part of this specification, and in which similar parts are indicated by similar characters,

3o Fig. 1, Sheet 1, is a perspective sectional elevation of the stove complete. Fig. 2, Sheet 2, is a partial sectional view showing the lower portion of the stove and the arrangement of the revertible fiues for heating the base of stove. Fig. 8, Sheet 2, is a section of the upper part of the stove, to show more clearly the operation of the hot air drums. Fig. 4, Sheet 2, is a partial interior view of the back plate and base of the stove, showing the hot- 4o air reservoir and the division of the base into hot and cold chambers. Fig. 5, Sheet 1, is a crosssection on the line a: 00,0: 00 of Fig. 1, showing the three-sided drum, in all of which- A represents the base or ash-pit section; B,

5 the fire-pot or illuminated section; O,the hot drum or magazine section; D, the hollow base;

E, ash-pit; F, grate; G, lower fire-pot; H, up per fire-pot; I, magazine; J, dome with a movable top; K, upper combustion-chamber;

0 K, lower combustion-chamber; L, escape-pipe or uptake for heated products of combustion;

M, hot-air reservoir; ll hot-air duct leading to the room above; N, cold-air openings in stove-base; N, revertible flue; N return-flue into uptake L from the hot base; P P, cold- 5 air pipes in interior of the stove; R, main damper; It, dome-plate damper; R dust-flue damper; S S, partitions dividing the hollow' base into hot and cold air chambers; T, dustflue from the ash-pit; U, revertible flue from the dome to the uptake; V V, ahot-air drum; V, apertures in the rearplate communicating with the hot-air drum and hot air reservoir; V cold-air inlet from the front of the stove into the hot'air drum; \V, a register placed between the stove and pipe M, to distribute a portion of the hot air from the reservoir into the room in which the stove is placed; X, a central divisionpartition having an opening Y, and Z the inlet from the magazine-section into the revertible fiue N.

The stove may be operated by direct draft on turning the" damper It to give a free passage into the uptake, also as a single or double heater. 7

The construction of the stove is as follows: We have below the ash-pit plate a hollow base divided by partition S X S, the division X having a passage, Y. The space between S and X communicates with the rcvertible draft- 8o 'flue N, and the space between X and S with the updraft-flue N Above the ash-pit we have a self-cleaning grate, F, preferably of the La Rue pattern, and the lower fire-pot, G, having a combustion-chamber, K, and above that the upper fire-pot,I-I,with its combustionchamber K,within which is suspended a magazine, I, the magazine provided with fore-andaft fingers at its base. In the' magazine-section we have on the .right and left and front 0 side of the stove a hot-air drum, V, the exterior casing of the stove forming three sides of the same, and a threesided integral partition, placed from one to two inches away from the magazine, forms the interior inclosure of 5 the drum, a horizontal plate closing the base, and the dome-plate the top of the same. Cold air is admitted by inducts V and the heated air is discharged into the hot-air reservoir through educts V. Cold air may also be in- 10; troduced into the hot-air drum by connection between the same and the base by pipes P P.

' a sufficient distance to place between the stove l ascending pass through the dome-plate, cirrevert down the flue U, and thence into the I The magazine-section has the outlet or up take L, controlled by a damper, R, and the inlet Z to the revertible flue N is also provided with a damper, and weplacein the dome-plate a damper, R, for indirect draft. The indirect revertible flue U from the dome has a direct connection with the uptake just beyond the damper B when it is closed, and the uptake also has direct connection with the updraftflue N 2 by a passage into the same. All the inlets have the ordinary stove-dampers for control. The ash-pit is connected with a dustfiue, T, by a damper, The hot-air rcseri voir is a jacket connected with the rear plate of the stove, and rests upon the tines N N, and is extended in the rear of the back plate and the hot-air pipe M an ordinary sliding registerflV. The pipes P I, when used, may be of cast or wrought iron.

The operation of the stove is as follows: Fire is first started upon the grate F, the damper B being fully open. As soon as the fuel is ignited the second or upper fire-pot is filled, andlastlythe magazine. After the-fire is in good condition, and only a moderately warm stove is desired, the main damper R is closed and the dome-plate damper It opened. The products of combustion then rising from the lower fire-pot pass through and mingle with the products of the upper fire-pot, and

culate around the head of the magazine, and

uptake. Or, if a hot stove is desired, the

dampers R and R are both closed and the inlet Z into the fiue N opened, the heated products then filling the magazine-section, revert down the line N into the base between S and X, and passing through X by the passage Y return to and up the flue N and thence into the uptake L.

lVhether operated as a direct or indirect draft parlor-heater, the cold-air chambers, with their connection with the hot-air drum by the pipes l? P,\vill assist in passinginto the same a supply of heated air, and will thereby increase the useful effect of the stove and create a circulation of the air in the room.

e do not claim the cold-air pipes 1? per se, only in so far as a combination is shown to exist between the cold-air chambers of the hotbase stove and the hot-air drum of the same,having already claimed the said pipes in combination with a cold-base stove in said prior application, as above stated.

Having shown the advantages, arrangement, and operation of our store, we desire to secure by Letters Patent the following claim thereon:

In combination with a double firepot square cross-sectioned stove,as described, provided with a hot-air base and cold-air chambers and pipes 1,the three-sided hot-air drum V, located in the combustion-chamber K, the three sides of its inner boundary being cast integral with each other, its base plate having a passage, V for cold air from the exterior, and its rear plate having passages V for hot air to pass from the interior into the reservoir M, substantially as and for the purpose specified.
